had laser hair removal and down the line noticed my upper lip paler than the rest of my face. It's been a while and it seems to not tan when im exposed to the sun...could this be permanent by the way the hair still grows.

Hypopigmentation from Laser Hair Removal
Laser hair removal can cause hypopigmentation (white spots) by destroying the pigment making cells in the skin which are "innocent bystanders". Fortunately this is usually temporary but it may take quite some time to re pigment. In the meanwhile, be care to use a sunblock to prevent a burn, especially in Texas.
Skin color change following laser hair removal
In my experience, it is more likely to have increase in pigment following laser hair removal. If inflammation following treatment occurs pigment can be stimulated resulting in darker coloration of the treated area. In the absence of inflammation or a burn following laser hair removal a drop in pigment would be unlikely. However, if there was a reduction in the number of darker hairs on the upper lip visually that would cause the lip to appear lighter.

Post inflammatory loss of pigment is often permanent after laser hair removal. This is because the heat of the laser destroyed the melanocytes in the skin that produce pigment.
Lighter skin color after laser hair removal
There are multiple variables that need to be considered to determine if pigmentation will return after treatment with laser hair removal.. If a patient has dark skin color, the wavelength of the laser needs to be considered. Longer wavenlengths penetrate deeper and spare the epidermal melanin target. If someone tans prior to the treatment that can increase the epidermal absorption of the energy and decrease the effectiveness of the laser from reaching the hair follicles. The diameter of the hair shaft and color of the hair also determines the absorption of the energy. The longer the time in months after the procedure is an indication of the possible long term hypopigmentation or permanency. A dermatologist may be able to examine the skin with a Wood's light to see if there is some pigment (hypopigmentation) or no pigment (depigmentation). There is hope but don't try to tan to improve the light color as it will accentuate the difference by darkening the surrounding skin and subject you to long term risks of ultraviolet damage. Sunscreen is important.
Discoloration and Laser
Hyperpigmentation or darkening of the skin is much more likely a result from laser hair removal due to thermal damage to the skin from the intensity of the laser energy. However, just like sun damage, the effects can be darkening or lightening of the skin. While usually temporary, hypopigmentation is notoriously difficult to treat and may require a wait-and-see approach.
